Rodax nv
About us
Rodax develops, produces and installs temperature sensors worldwide for the oil and gas extraction, chemical and petrochemical, pharmaceutical and energy sectors.
Rodax was founded in 1983, and focuses on international industrial markets, with a program of all-round temperature sensors and composite products. Working closely with global customers, we have already provided many highly reliable solutions for standard and custom applications, such as heavy duty vibration proof sensors, furnace and boiler thermocouples, multipoint reactor temperature assemblies and more.
Within these sectors we offer a total package of temperature sensors, with an emphasis on a number of products and associated services: - critical temperature measurements in petrochemical furnaces, flares or incinerators - critical temperature measurements in steam boilers - reactor multipoint temperature measurements - high vibration resistant temperature measurements for rotating machines such as compressors , turbines, generators, pumps, etc. In these segments we create a total service for global multinationals. We want to be a privileged partner based on first class services and products within an economic context. Rodax joined the 8-Lakes group in late 2015.
Products & services
Rodax Furnace and Boiler Thermocouples
Rodax Furnace and Boiler Thermocouples are installed in challenging environments. Therefore, special care must be taken in defining the right product and choice of materials for the process involved. In order to maximize and maintain safety of operations, tube skin temperatures need to be precisely monitored. Afbeeldingsresultaat voor rodax europe That is why Rodax Furnace and Boiler Thermocouples have been designed to meet strict objectives: Rodax criteria for correct measurement: - Choosing the best mounting method and sensor form. - Defining the materials needed in dialogue with the customer. - Identifying the best way to conducting your measurement outside the furnace. Long life: The selected head type and sheath material are very critical to process conditions. Companies aim to increase time between stops, nowadays typically between 4 and 6 years versus a tube life design of 10 years. Tubes can indeed exceed the design life time when run at a lower than intended temperature. Our expert engineers will assist you in the choice of materials so you can save considerably on downtime and maintenance. Economy on fuel: Measuring the exact temperature is very critical to firing the furnace or boiler at an economic rate. Increased tube life and tube reliability: Tube failures are most commonly due to overheating. Economic firing of furnaces or boilers reduces material wear. Therefore particular attention must be paid to on-stream tube temperature monitoring. Coke detection requires a very accurate measurement method as well.
DRILLED BAR STOCK THERMOWELL
Our thermowells are machined and drilled from solid bar stock. This results in a non-welded unit. High accuracy machines are used to ensure concentricity of the bore with respect to the outside diameter and a consistent wall thickness over the full length of the thermowell. Our bar stock thermowells with straight stem have been designed for various fluids and pressure applications. Metric and fractional connections. These temperature sensors are designed for temperature measurement in harsh, high temperature and abrasive environments. The materials we use have excellent chemical resistance properties, high abrasive and thermal shock resistance, very low permeability and a high mechanical. Technical specifications – Tolerances : all dimensions +/- 1 mm except B : +/- 0.15 mm – Standard finish 1.6<Ra <3.2 μ – Vent hole D 3 mm – T standard 57 mm.

Flue gas temperature sensor
Optimal performance in extreme conditions Model of a coil outlet thermocouple Flue gas temperature sensors are designed for temperature measurement in harsh environments such as high temperatures (max. 1600° C) and abrasive media. All ceramic materials are available. However, we prefer to work with Silicium Carbide as this material has excellent chemical resistance properties, high abrasive resistance and thermal shock resistance, very low permeability and a high mechanical strength compared to other ceramics. All wells are made to customer specification.

Exceptional length with reactor temperature measurement system
Some time ago, Rodax received an order from Shell in Rotterdam for a reactor temperature measurement system. This system has an exceptional length of 34 meters and can withstand operating pressures of 600 bar at 450°C. The whole weighs more than 1 ton. The system was transported by Van Egdom. The sample had a total length of more than 40 meters, which meant that it had to be transported at night. Rodax is a specialist in building temperature sensors with exceptional specifications for the oil and gas industry. The customers are the top international companies such as Shell, Esso, BP, BASF, etc. We export these systems worldwide. We are active on the international markets and exports not only to Europe, but also to the Middle East, the Far East and Russia.
